Nicolas-Jacques Conté (1755-1805) was a French engineer, scientist, and inventor.

An account of his life and work here [1]

Conté invented the modern pencil lead at a time when the French Republic was under economic blockade and unable to import graphite from Britain. Lazare Nicolas Marguerite Carnot asked Conté to create a pencil that did not rely on imported material. After several days of research, Conté had the idea of mixing powdered graphite with clay and pressing the material between two half-cylinders of wood. He received a patent for the invention in 1795, and formed la Société Conté to make them. He also invented the conté crayon. [2]
